This looks like a good read and John makes some good suggestions look for key word: Hamiltonian, Feynman,Lagrangian.
I had physics at cal poly in75 and it was cool. I watched, on you tube, a physics lecture at Stanford on string theory that was also cool. Looking forward to reading!
Hoax is a funny word to hear. Climate change is a political idea and science uses language more carefully than political scientists do. We all know that the most moronic way to motivate people is to scare or bait them. Wise people are not either scared (because they have courage) or tempted by the chance of gain (because they are moral), so lets not follow the crowd without thinking.
